According to an article in FineWoodworking by Prof Roman Rabiej, Cherry being glued on a quarter sawn face needs 250psi. My table top is 78" x 1.75 along the seem which calculates to 34,000 psi required.
Using all my large clamps (12 pipe and 5 K Body) and giving a maximum pressure (due to my hand strength) that totals out to 20,000 psi.
Do I really need to go out and purchase 10 more pipe clamps? I am almost ready to glue up the dining table top that I have hand planed 3 boards to prepare. The final top will be 82 x 42 (including breadboard ends) and is my most important project to date. This is beautiful cherry that deserves to be done right.
Any suggestions? Below are photos showing my clamp base with built in panel clamps and a frame to support the pipe clamps. 10 clamps will be from underneath and 7 will be applied from the top.
